Anti-Reflection (AR) Coatings (Glass Using Nanomaterials)
|Anti-reflection (AR) coatings using nanomaterials on sheet glass |
Our technologies are based on the expertise in synthesizing nano-particles with precisely controlled size, physical, chemical, and electronic properties. We currently have developing single layer AR coating of highly porous silica thin film. The AR property on both coatings are excellent and can provide 5% to 8% enhancement of transmission. Our nanomaterial AR coatings can provide up to 99% transmission.
These coatings are applied to substrate surface by a wet coating process (i. e. dip).
The wet coating process results in significant improvements in processing speed and cost over existing deposition-based methods.
Photovoltaic modules equipped with antireflective glass show significant performance benefits compared to conventional modules. In addition to the technical advantages, modules with antireflective glass exhibit a distinct reduced glare and pleasant optical appearance.
B. Solar thermal:
In solar thermal collectors generating hot water for domestic use, antireflective glass as cover sheet for the collector also results in a beneficial thermal yield.
Beside the focus of solar applications, antireflective glazings can be advantageously used in other fields of high demand on light and energy transmittance. In the last decade, Europe exhibited a growing rate of vegetables and flowers which are grown in greenhouses. A 6% transmittance increase results in a 6% higher crop yield.
D. Architectural (protection glazing):
In architectural applications the antireflective glass can be used as a tailored system for protecting historical facades and ancient glazings. For this application, color neutrality is of crucial importance since the optical appearance of the building should not be influenced. Our antireflective glass can easily be adjusted in its reflectance color by varying the coating thickness.
Antireflective glass cut visible light reflectance to less than 2%, while allowing more visible light to pass through than even clear float glass. In addition to its anti-reflective properties, antireflective glass blocks over 99% of UV transmittance to protect interiors and contents. Antireflective glass is not only ideal for typical anti-reflective uses such as museums and displays, but a practical choice for retail storefronts, showrooms, and a host of applications where an anti-reflective product was never an option.
